My Three Angels by Sam and Bella Spewack
It is Christmas Eve in the tropical prison colony of Cayenne. Felix Dulay,
a hopeless storekeeper, is fearfully awaiting the arrival of the owner, Gaston.
Providence has given the Dulays three guardian angels ... three Convicts!!!
In no time at all they have cooked Christmas lunch ~ and Felix's books ~
and they are about to set their own executioner on to Gaston
for his cruel behaviour!
